Thanks to Minion and Ashy & a few other gurus here, I was able to successfully convert the AC3 audio stream in my downloaded DIVX movie to a WAV (using VirtualDub to extract the audio stream to WAV, then changing the resulting WAV file extension to AC3, and then using HeadAC3he to convert the AC3 file into a "real" WAV, that TMPGEnc could use.
Next, I used TEMPGEnc's wizard to create the MPG.... using SVCD, and NTSC 704X480 templates. 2 hours, 49 minutes later, I tested the resulting MPG. (It looked approximately the right size... the original AVI was 717,480...the WAV was 810,121, and the MPG was 1,469,776..... and this was just "CD1" of the downloaded file! I still have another one to process! Obviously, I would need to merge and cut the two CD downloads to put them on 3 or 4 CD's, eventually (which seems excessive, actually).... But the quality of the picture and sound of the AVI was awesome on my computer, so I persisted!)
One message that I got from TEMPGenc after the MPG was processed, that I wondered about, was "Stream read error". I didn't know what that meant, but I am guessing that it means that I can't getting any picture! But I had to test that anyway, with 2 hours, 49 minutes, and a Gig and a Half already invested.
I cannot get any picture in Windows Media Player, Divx player, or VCD Cutter players. The sound is fine in all players (my former problem, before using HeadAC3he was that the sound was too jittery to comprehend on the MPG, but the picture was still awesome.)
Am I skipping some step here? I am wondering if I need to somehow extract the video stream and merge it with the audio stream created by HeadAC3he... but I am not sure this is what I need to do... and if I will be able to maintain synch, if I do that, before encoding with TEMPGenc.
Please keep replies at "newbie" level. I have read a great number of posts here, but there are 159 pages, so I don't understand a lot of the terms yet... even though I look them up at another site that has a glossary.

I am trying to convert an .avi file to a .mpg file so that I can burn it to SVCD. Also, are there any "newbie" guides on how to do this, or maybe a different program to try? I will be burning with Nero. I have successfully made SVCD backups of DVDs, but this is my first attempt at making an SVCD from a .avi file I downloaded. Also, the .mpg file that I do get from this attempt has no sound. Any ideas on this one? Thanks for any advice ya'll can give!
My source .avi has 25 fps. However the frame rate in the "Source range" window shows 30 fps if the "DirectShow File Multimedia Reader" priority is set to 1 in the "Enviromental settings" (VFAPI plug-in).
It is only a bug if when you start encodeing it encodes it at 30fps instead of 25fps...After you have done your settings and you go back to the main screen, what does it say the frame rate is set to at the bottom of the Tmpgenc screen??
Check out the latest version of the TMPEG Batch List Creator. The New version makes it even easier to select multiple video files to convert using TMPEG.
That file is a DVD2AVI project file.
Ensure u do not move,rename or delete either the .d2v file or its folders or the vob files used to create it. In fact don't change anything until u have completely finished with the file.
If this isn't the case then simply copy this file DVD2AVI.vfp from your DVD2AVI folder into your TMPGenc folder where the TMPGenc.exe is located and it should work.

It is a dvd that I copied to my hard drive with cladDVDXP.

Is it possible with TMPGenc to get the file information of a
MPEG1/2 video file (type, framerate, screensize, etc.)? Virtual
Dub mostly will not load MPEG file. Often you'll find (music)
video files on the web which you can play with your Windows
media player but this one won't give you information at all.
In Audio only, you get an elementary Stream.
The other Option creats a system Stream. But there are not much Ideas how (and for what) to use them, if they are Video or Audio only.
Elementary Streams are very usefull if you plan to use an other Multiplex-Tool or to create a DVD.
It can go out of sync for a bunch of reasons, If you are encodeing to a different frame rate than the original file you can have sync problems, if the audio was off set in the avi by who ever created the file that would cause de-sync...Sometimes a AVI file will say that it is 25fps say but it is actually 24.97fps or something and when you encode it it goes out of sync cuz it isn"t actually the frame rate it says it is...These are a few reasons why it happens and there are more but seing as how we have no information about your avi file all we can do is Guess.....
I am just wondering if Tmpgenc is a 100% vcd compliant. I have a portable vcd player (napa dav-311) and it is apparently very picky about which encoder have been used when encoding the mpeg files. For some reason it doesn't like tmpgenc at all, and the playback gets all jerky when playing the vcds. So far the only encoder i have managed to find that make smooth playing mpegs are the "video impression" program that ships with roxio easy cd creator. That program sucks because it is too slow and doesn't produce nearly as good images as tmpgenc does. Does anyone know what to do???
No TMPG does not produce 100% VCD compliant MPEG files. This is why you are having problems.
The reason is due to the way TMPG multiplexes the streams together. The solution is to download Phillips Video cd 2.0 toolkit and use the multiplexer to re-mux the MPEG.
De-multiplex the MPEG to seperate video and audio streams with TMPG then use the VCD toolkit multiplexer to re-multiplex them together. This should create a 100% vcd 2.0 compliant MPEG which your player should be able to play fine.
I suppose you can encode Mpeg1 to Divx, but Virtual Dub would be better for that cuz that is what it is made for..To turn a Mpeg1 file into an avi file you just load the Mpeg1 file into Tmpgenc and then go to "file" to "Output to" then to "AVI" then a window will pop up with and dialog on were to save the file and there you can choose the Codec to encode with and the codec settings.the when you click "Save it should start makeing a AVI file with which ever codec you chose that is installed on your system..
I have 2.57 and was wondering about some of these settings.
- What does changing the bitrate do?
It is at 1150 - if I go to 2200 will that make the output better?
If I change the min value to a higher value would that make output better?
- Is 2 pass VBR better than VBR auto?
If I choose 100% on the quality of auto would that give me better output?
I have an avi file that I want to view on the computer at 640x480 and there just seems to be a lot of noise when it is playing. What I mean is that when a door is opening it is almost like it is slightly breaking apart.
Viewing the origingal file on a NTSC monitor show a very sharp, high res out put but after going thru compression it seem crappy.
The Quality of the encoded mpeg is directly related to the Bitrate used to encode it and the quality of the source file..The best encodeing method is the "CQ" or "Constant Quality" method, it is better than the 2-pass method with half the encodeing time..And the higher the resolution of the mpeg the higher the bitrate should be..For regular VCD resolution usually about 1650kbs should give you fairly good results but even higher is better, when useing the "CQ" method putting the Minimum at 1000kbs and max at 5000kbs with the quality at about 85 you should get very good results...But the quality of the Output can only be as good as the quality of the input...
